Hi I'm new to the impreza world, iv just picked up my first one been tinkering the last few days with it, it's a 2004 wrx with cat back, panel filter, bov and remap. 

Anyway I'm going to install a boost gauge that iv already bought along with a single pilla pod to mount it, only issue is how do I get the vacuum pipe up behind the dash and to the back of my boost gauge neatly? Will it fit though without cutting the dash? 

Remove the standard pillar, drop your vac hose and wiring down. Then look underneath and boom! Jobs done!
